| Abstract: | A new method for the determination of the QCD condensates from low-energy hadronic data is proposed. It generalizes the usual QCD finite-energy sum rules, taking into account explicitely the truncation error of the high-energy QCD expansion. The method is applied to the e+e– annihilation intoI= 1 hadrons, indicating a rather large domain for the values of the gluon and four quark condensates. |
